Thanks for voting!
The results are what I had expected.
I've made a 1400 US$ investment and upgraded my development environment to Delphi XE5 and the compatible version of the commercial Developer Express components.
The roadmap for NXT Solaris now looks like this:
1.) Move current version of my code to XE5 and release closed source 32-bit and 64-bit versions for Windows (only trivial changes).
2.) Refactor my code to a MVC architecture, so that I can create separate GUIs while using the same version of the business logic code.
3.) Create new GUIs for Windows and OS X using the same business logic, but based on the cross-platform Firemonkey libraries (technically possible targets are Windows, Android, OSX, iOS). The GUIs will not be as sexy and powerful as the closed-source Windows version, though (no Ribbon interface, no filtering, sorting, grouping in data grids, not so many icons etc..), but will still very much resemble what is in the closed-source client.
4.) Release open-source Windows version (32 and 64 bit) based on FireMonkey.
5.) Release open-source OSX version based on FireMonkey.
=> At this point you could decide if you want to use the open-source Windows and OSX version or the closed-source, slightly more sexy and powerfull Windows version.
I will reevaluate if I do versions for Android and iOS at a later point, however I will keep this option in my mind when refactoring the code in step 2. The poll shows that 25% of all voters would use it, but it also depends on which alternatives are available at that point. I would also need to invest another 500 US$ to go mobile and I don't want to do this now.
I will not target Linux, since I technically can't. Someone else might want to jump on this.
I don't know the timeline for the roadmap, so don't ask. ;-) I'll take a week of from my day job next month to get a bit of this done.
A big thank you for your huge efforts to get this thing open source
The results are what I had expected.
Just a quick reminder: Your poll was posted in bitcointalk.org, a nerd forum for crypto freaks. That should bias the results
We work for mass adoption, even the more sophisticated clients should be able to run on the big systems (PC, MAC are the most important, afterwards iOS and Android). Keep that in mind, please.
Big thanks again!
